Well to start the fuel lines are on the wrong side of the car so you have that to deal with. The fuel pickup is differnet however you could replace it with one that doesn't have a pump built on. Back to the engine. You will need a timing cover from a carbed engine any 5.0L up to 86 will work. HO and non HO engines are the same. You wil need the eccentric off the cam of the carbed engine. thats about all I think you need, the rest line fuel lines and such you can make.
